Mabs,
You have the cost of demolition as well as the build. You can call Kola Construction- google it. Or call Centaur Construction at 704-622-2126. Or call Jim Potter at 704-455-6572. Tell them that Robin Faison recommended their services. Your cost is dependent on building materials used, foundation of the house, labor charge, etc. Would guess at least $80sq/ft- but after 3 quotes, you should have a general idea. Allison Pell is a good architect if you need one, 704-607-0454.

I think there are way too many variables to truly give you any kind of meaningful number. But, if you like I would be happy to email you the names of some great general contractors that could give you some free quotes.
